Definition
Plain language
DeepMind's system that combined neural networks with formal proof tools to solve olympiad math problems.
As stated in the literature
A specialized DeepMind system pairing language models with Lean-based formal verification and search to attain medal-level performance on IMO problems.
Why it matters: It showed that pairing LLMs with formal verifiers can reach olympiad-level math, demonstrating that hallucination-free math reasoning is achievable.
For example, AlphaProof attempted IMO problems by translating them into Lean and searching for proofs the compiler would accept.
